SIDEWALK-ELEVATOR.

Specification of Letters Patent.

Patented Jan. 16, 1917.

Original application filed September 22, 1915, Serial No. 51,923.Divided and this application filed February 15, 1916. Serial No. 78,367.

T 0 all whom it may concern.-

Be it known that I, JENS S. LINDHOLM, a citizen of the Danish Monarchy,and a resident of Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in, Sidewalk-Elevators, of which the following is a specification.

This invention relates to sidewalk elevators and has for its object theprovision of certain constructions for safety in order to preventaccidents while operating the elevator.

Another object of the invention is the provision of an open-workelevator platform to admit light and air to the lower levels when theelevator is level with the sidewalk.

This application is a division of my allowed application Serial Number51923, filed September 22, 1915.

Accordingly my invention comprises such parts and elements incombination with a sidewalk elevator as hereinafter set forth, claimedand as illustrated in the accompanying drawing in which- Figure 1 is asectional view of a sidewalk elevator embodying my invention. Fig. 2 isa plan view, and Fig. 3 is a detail view of the platform.

Referring to the drawing the numeral 10 represents the elevatorcomprising the platform 17, a framework of bow irons 18 and 19, one inthe rear near the building line 20 and one in front.

23 is a cross brace secured to the front bow iron 19.

21 represents the hoisting means.

14 and 15 are the sidewalk doors pivoted at 16.

In order to prevent accidents to persons and especially children causedby falling in over the elevator as it descends, I provide a wire shield35 between the bow irons and support the same further by cross bars 36and a bow bar 37 which also serves to strike the doors in the middle toopen them in the usual manner when the elevator ascends. I furtherprovide front protecting bars 70 to close the space at the top betweenthe bow irons 19 to prevent people from falling in over the elevatorplatform endwise. This is particularly useful when the elevator israised slightly above the sidewalk for ventilating the space below.

A sidewalk elevator is sometimes left for a considerable time at thesidewalk level and in order to provide light and air for the spacebelow, I provide an open-work platform which may consist of flat irons38 and lattice work 39.

It will be seen that the improvements pro vided by this invention arevery simple, yet they are valuable and useful in providing protectingmeans against accidents without in any way interfering with theoperation of the elevator or materially changing the constructionthereof.

It is not necessary that the improvements referred to be provided in theidentical form or manner herein disclosed, and I claim all such changesand modifications which properly come within the principle of theinvention and the scope of the claim.

I claim A sidewalk elevator comprising a platform and bow irons, asafety open-work top between said bow irons and protecting bars securedat the front of the said elevator to the one bow iron thereof.

Signed at New York in the county of New York and State of New York this14th day of February A. D. 1916.
